I was thinking to start a network where people could become hosts to organize date parties of certain interest and age group at their house.It will be a better idea to meet instead of going to bars or trying to select online. Any comments?

Sure. But there are flaws. It’d just be a party with friends of friends anyways. Nobody wants to host a party to strangers at their own house. So it’s not so much a whole new dating scene. Just friends hanging out having fun rather than a singles scene to get a date.
